Title: Hydraulically-operated power transmitting coupling
Inventor: YAMADA TAKEHISA
IPC: F16D31/02
Filed: 1991-10-23
Abstract: PURPOSE:To take large compression ratio, which serves as a spring constant, by using a return spring such as utilizing compressibility of gas, in the case of a coupling provided with a plurality of plungers driven by a cam surface and impulse-moved against the return spring. CONSTITUTION:In a rotor 5 rotated through an input shaft 6, a plurality of plunger chambers 7 are formed in an axial direction, and a plunger 8 reciprocated in cooperation with a cam surface 2, having two or more crests, of a cam, connected to an output shaft 3, is fitted into each plunger chamger 7. The plunger 8 is energized in one direction under pressing of a return spring 9. Here as the return spring 9, an air spring, formed in the plunger by fitting a piston 32 into a cylinder chamber 31 injected with gas, is used. In this way, a large load can be obtained in a cam curve part (in the vicinity of a maximum stroke) to improve a follow-up characteristic of the plunger 8 to the cam 1.

Title: Prevention of crucible fracture and device for preventing crucible fracture
Inventor: SHIRAISHI YUTAKA
IPC: C30B29/06
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for preventing fracture of a crucible when stopping pulling up on the halfway. SOLUTION: A hollow vessel 4 is dipped in a molten liquid 3 to absorb the volume-increasing part by solidification of the molten liquid 3 when stopping the pulling up and solidification of the molten liquid 3 in a quartz crucible 2 in the method for preventing fracture of the crucible. When the molten liquid is solidified in a state in which the hollow vessel 4 is dipped, the molten liquid 3 starts the solidification from the surface of the molten liquid 3 to confine the molten liquid between the solidified surface layer and the quartz crucible 2 and solidified to increase the volume, but the quartz crucible 2 and a graphite crucible 1 are not destroyed because the hollow vessel 4 is crushed by the increased part of the volume.

Title: Paper sheet transport force control device
Inventor: EOMO KYORI
IPC: B65H26/00
Filed: 1990-10-15
Abstract: PURPOSE:To enable stable paper sheet transport operation by constituting so as to select a transport force suitable for paper sheets when paper sheets of different thickness or paper sheets for special use are used. CONSTITUTION:A sensor 1 detects the thickness of continuous paper sheet 10 to be transported. Then, a control part 2 receives the signal from this sensor 1 and judges the thickness of the continuous paper sheet 10 thereby, and outputs a control signal 11 to a motor 4. The motor 4 which receives the control signal 11 from the control part 2 rotates by an angle corresponding to the transport force designated by the control signal. The rotation of this motor 4 causes a cam 5 which is directly connected thereto to be rotated and a lever 6 is driven by means of the cam 5. The operation of this lever 6 causes the deflection of a plate spring 7 to be changed. The change in the deflection of this plate spring 7 causes a change in the contact pressure of a feed roller 8 with a feed roller 9, resulting in the required transport force.

Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a camera with simple constitution and a self-timer. SOLUTION: By winding the winder of a timer, load is exerted on a spring. The input gear unit 318 of the timer is driven by the spring. An intermediate gear unit is arranged in series between the input gear unit and an output gear unit. A linkage including the winder moves between a start position and a finish position together with a gear train. The check member of the linkage captures a shutter release when the linkage is at the start position and the shutter release is at a stop position. When the linkage is at the finish position, the check member is released from the shutter release. When the linkage is at the start position and a timer release arm 330 is at a 1st position, the arm 330 comes in contact with the contact surface 362 of the intermediate gear unit and stops it. When the arm 330 is at a 2nd position, it comes off the intermediate gear unit.

Abstract: PURPOSE:To substantially obviate generation of distortion, etc., arising from a temp. change by forming prism bases of black ceramics having a specific coefft. of thermal expansion and mounting CCDs on the metallized surfaces provided on the prism bases, thereby constituting the title spectroscope. CONSTITUTION:The plural prisms 2a-2c are combined and both the end faces thereof are held by the plate prisms 1 consisting of the black ceramics having 6-10X10<-6>/ deg.C coefft. of thermal expansion.

Abstract: PURPOSE:To prevent the influence of a hindrance on a driving system by fixing a lens hood in the optical axial direction of a lens-barrel, and supporting the lens hood on a rotational lens-barrel, so as to attain slipping in a rotational direction at constant torque or more. CONSTITUTION:An optical system 3 is fixed on the fixed barrel 1 of the lens- barrel, and a front frame 2 provided with an engaging groove 2a, is screwed so as to be rotationally drawn out. Then, a driving pinion for AF 4 transmits rotational force to the front frame 2 by the drive of a motor. In an AF state, the front frame 2 is turned via the pinion 4, the optical system 3 is drawn out in an axial direction while being rotated, according to a twisting lead with the fixed barrel 1, to execute focusing, and even if external force is imparted to the lens hood 5, the front frame 2 is slipped and kept rotating. In an MF state, the connection of the pinion 4 with the motor is interrupted by an A/M changeover switch, so that when the lens hood 5 is rotated by a hand, the front frame 2 is drawn out in the axial direction to execute the focusing. The rotation of the lens hood 5 and the lens-barrel is regulated by friction connection, and when great rotational force is imparted to the lens hood, the slipping is attained, and required torque or more is never imparted.

Abstract: PURPOSE:To enable resin sealing of an electric part having small loss in cost by molding a resin unit to be discarded after resin sealing with cheap resin material. CONSTITUTION:A tablet 1a is formed by solidifying relatively high moisture- resistant epoxy resin powder. Then a tablet 1b is made by solidifying lower- grade cheap epoxy resin powder. These two tablets are unified by adhering with epoxy resin. A lead frame 5 is mounted on a cavity 3 in advance.
